Advice for requirements for a unRAID home server - Page 2

post #11 of 24
FakeRAID isn't always chipset raid...FYI.

There are three different types of Raid:
-Hardware
-Firmware
-Software

FakeRAID was a term given to low-end onboard raid...basically a software raid built into a motherboard, at a "firmware level".

Yeah I do have one in place already.
Budget honestly I'm not too worried about but I don't want to go overboard, I'm looking at about £100-250 for the components without drives (About $160-400)
For this build it's all about power conserving for me while still getting decent performance, which honestly I've never done before. Looking for mostly a nudge in the right direction so I can look into it a bit more.
Thanks smile.gif

FYI, I did this with 4 2TB WD RE4 drives, freenas (software), a c2duo e6300, and a used 3ware 9550-SXU-12 (12port hardware raid 0,1/0,5/0 card). they can be had for cheap on ebay, and that way if a drive dies you don't lose data. I really dislike the idea of losing 2+TB of data because one drive quits unexpectedly.

I used two older 250GB drives in raid 1 (off the same card) as boot media, and I have 6 ports left for when I need more storage.

I get 90-100MB/s of throughput on my lan when moving large files, btw.

To be honest, I'm not too sure about FakeRAID. I guess what I should have said originally is "not all chipset raid, is FakeRaid."

Some high end motherboards have quality controllers integrated on the motherboard...ASUS server boards come to mind (ones that don't require the PIKE card, that is).

Hi Alex,

I have been using Unraid for two years now... rock solid nas!!

Unlike other NAS software unraid only requires ata/sata port/interface to work and you can mix all sort of disks, size and speed does not matter! And you dont have to spend money on some hardware raid controllers smile.gif

I'm using AMD Sempron 140 very cheap cpu and some MSI motherboard with onboard 1Gb ethernet and 6 sata ports and it has been running 24/7/365 for 2 years now without a problem.

Only thing to remember is that the parity drive can not be slower or smaller than any of your array disks.


You can even take one of the disks out of the unraid server and plug it in your windows machine and the windows can see it and can read of it!

So it's basically raid 3 without synchronization or striping - I'd rather have raid 5, then performance isn't limited by the parity drive.

Thread Starter 
Thanks for the posts guys, I think I've managed to scrape together some parts, doing a bit more research before I buy. Probably going to customize a case as well make sure that its as quite as possible.

So far I'm still leaning towards unRAID, going to do some more research before deciding though.

Thanks again smile.gif

As far as power consumption, you generally only run into problems buying power-conscious drives for RAID arrays.

My file server in my sig, for example, idles at ~78w DC load with 8 drives idle-but-still-spinning.
This raises to ~100w when writing to all of them concurrently at gigabit-saturating speed.

If you're making power decisions a more efficient PSU will provide a higher gain and less issues than 'green' drives that occasionally will drop off of your array due to power saving features.
